Miranda curated the auction that featured more than 400 lots of her clothes, jewelry, accessories and more. The proceeds benefit her MuttNation Foundation, which Miranda and her mom Bev started in 2009. The foundation has successfully raised millions of dollars to aid organizations, government institutions and entities that build animal shelters for better care and increased pet adoption.

“I know it was just Thanksgiving, but it already feels like Christmas,” says Miranda. “It just means so much that we’re able to help so many more rescues and shelter pets, especially at this time of year. I’m incredibly grateful to my fans for making this auction such a great success. It almost makes me want to clean out my closet more often!”

Among the items with top bids were Miranda’s silver and black cuff with crossed pistols, her video-worn Idyllwind cowboy boots and her handwritten lyrics to “Bluebird.”
